Latest Patents

One of Dunn's latest patents is titled "Shading and texturing 3-dimensional computer generated images." This invention provides a method and apparatus for dealing with punch-through textures by supplying data that defines a group of surfaces representing each object in an image. For each elementary area of the display, a depth value is generated for each surface of each object based on the distance of that surface from an image plane. Shading and texture data are then applied to the surfaces. A determination is made to check if any texture applied to a surface is fully opaque. The depth values for opaque textures are stored at the appropriate elementary areas. Subsequently, the depths of surfaces from other objects are compared with the depth values for the opaque objects, allowing for the discarding of surfaces or subsequent objects that have a fully opaque surface closer to the image plane than the surface being considered.

Another significant patent is the "Method and apparatus for performing arithmetic division with a machine." This invention allows for arithmetic division to be implemented using either hardware or software. The process begins by storing the reciprocal of each nth value in a range from 0 to X, where n is greater than 1, along with the differences between the reciprocals of the intervening n-1 values. A mantissa and an operand for arithmetic division are received, and one of the stored reciprocals is retrieved based on the most significant part of the received mantissa. A set of differences is retrieved in response to the least significant part of the received mantissa. The differences and the reciprocal are summed, and the result is multiplied by the received operand, yielding the result of the arithmetic division.
